Arabic Recognizing Voice to Control Wheelchair & Obstacle Detection Features

This work describes wheelchair control using voice recognition and a digital controller based on PWM that sends speed warnings to ensure autonomous chair motion correction by using ultrasonic sensor data. The chair facilitates the handling of physically disabled people who cannot control the movement of their limbs. The wheelchair is powered by electrical power and the tire motors are controlled using a microcontroller and a voice recognition module that recognizes the voice of the user and provides the data stored in the memory of the user. processor to execute the command. The project was successfully implemented on the wheelchair and the results showed accuracy and flexibility in chair control.
